updated from the given bitmap, including any size

changes. Note that the CanvasHelper does <em>not</em> take

ownership of the SpriteCanvas object, nor does it perform

any reference counting. Thus, to prevent reference counted

objects from deletion, the user of this class is

responsible for holding ref-counted references to those

objects!
